'''FreeCAD''' 是通用且[http://en.wikipedia.org/wiki/Open_source 开源]的三维 [http://en.wikipedia.org/wiki/CAD CAD/MCAD]/[http://en.wikipedia.org/wiki/CAx CAx]/[http://en.wikipedia.org/wiki/Computer-aided_engineering CAE]/[http://en.wikipedia.org/wiki/Product_Lifecycle_Management PLM] 建模工具, 目标直指[http://en.wikipedia.org/wiki/Mechanical_engineering 机械工程]与[http://en.wikipedia.org/wiki/Product_design 产品设计],也面向更广泛的工程应用,例如建筑或其他工程领域。FreeCAD 以参数化特征建模为核心功能,基于模块化的软件架构而实现,可在不改动系统核心的的前提下进行功能扩展。

FreeCAD 建立于强大的几何核心 [http://en.wikipedia.org/wiki/Open_CASCADE OpenCasCade] 之上,采用 [http://en.wikipedia.org/wiki/Coin3D Coin 3D] 提供的与 [http://en.wikipedia.org/wiki/Open_Inventor Open Inventor] 兼容的三维场景模型,并提供丰富的 [http://en.wikipedia.org/wiki/Python_(programming_language) Python] 应用程序接口,其图形交互界面基于 [http://en.wikipedia.org/wiki/Qt_(framework) Qt] 实现。FreeCAD 能够确保在 Windows, Mac OS X 与 Linux 平台上运行时用户交互界面的一致性。

== 核心功能 ==

* [[Image:Feature1.jpg|left]] 基于 [http://en.wikipedia.org/wiki/Open_CASCADE Open CASCADE Technology] 的完整的'''几何核心''',对 brep, nurbs, 布尔运算与倒角 (fillet) 等概念提供原生支持,可完成复杂形状类型的三维运算 {{clear}}

* [[Image:Feature6.jpg|left]] 支持以插件(模块)形式对核心功能进行扩展的'''模块化的软件架构'''。所实现的扩展可以像一个全新的应用程序那样复杂,也可像 [[Scripting|Python 脚本]] 或所录制的 [[macros]] 那样简单 {{clear}}

* [[Image:Feature3.jpg|left]] 健全的'''参数化模型''',支持任意类型的参数驱动对象定制,甚至可[[Scripted objects|完全用 Python 编程实现]]{{clear}}

* [[Image:Feature4.jpg|left]] 可通过内建的 '''Python''' 解析器,宏或外部脚本操纵 FreeCAD 的全部功能,例如 [[Topological data scripting|几何模型创建与坐标变换]], 几何体的二维与三维表示 ([[scenegraph]]) 甚至 [[PySide|FreeCAD 图形界面]] {{clear}}

* [[Image:Feature5.jpg|left]] 支持'''标准格式'''的数据导入与导出,例如 [http://en.wikipedia.org/wiki/ISO_10303 STEP], [http://en.wikipedia.org/wiki/IGES IGES], [http://en.wikipedia.org/wiki/Obj OBJ], [http://en.wikipedia.org/wiki/Dxf DXF], [http://en.wikipedia.org/wiki/Svg SVG], [http://en.wikipedia.org/wiki/Universal_3D U3D] 与 [http://en.wikipedia.org/wiki/STL_(file_format) STL] {{clear}}


== 尚在开发的功能 ==

* [[Image:Feature7.jpg|left]] 具备约束求值的[[Sketcher Workbench|草图 (Sketcher)]] 模块,以实现具有几何约束的二维形状草图建模。目前 草图模块支持多种几何约束类型,可使用它们作为 FreeCAD 中其他对象的构建基础。{{clear}}

* [[Image:Feature8.jpg|left]] [[Drawing Module|工程制图 (Drawing sheets)]]模块,用于生成三维模型的二维视图,并能以 SVG 或 PDF 格式输出。该模块虽然仍缺乏许多功能,但是已经具备了强大的 Python 接口支持。{{clear}}

* [[Image:Feature9.jpg|left]] [[Robot Workbench|机器人仿真]]模块,可用于研究机器人运动。该模块目前已具备一个宽泛的图形界面,可仅仅通过图形交互界面进行机器人运动仿真。{{clear}}

* [[Image:Feature-raytracing.jpg|left]] [[Raytracing Module|渲染]]模块,可导出三维对象,以供外部渲染工具实现模型渲染,目前仅支持[http://en.wikipedia.org/wiki/POV-Ray povray],但是将来有望扩展到其他渲染工具。{{clear}}

* [[Image:Feature-arch.jpg|left]] [[Arch Module|建筑]]模块,支持 [http://en.wikipedia.org/wiki/Building_Information_Modeling BIM] 风格的工作流程,并兼容 [http://en.wikipedia.org/wiki/Industry_Foundation_Classes IFC]。建筑模块的设计与实现还在社区讨论阶段,见[http://forum.freecadweb.org/viewtopic.php?f=10&t=821 这里]。{{clear}}

== 手册 ==

FreeCAD 手册提供致力于提供有关 FreeCAD 使用的最好的文档,依赖于社区的努力该文当尚在撰写中,目前已有多种语言的版本。这份文档依然缺乏许多信息,如果你有空闲时间请给予[[Help FreeCAD|帮助]]!
